The Professor's Undergolems
During the raid on the Professor's castle, when Lok Lambert and Sophie Casterwill were going to fight the Professor, two Undergolem Titans hiding as statues attacked the remaining Seekers, Dante Vale and Zhalia Moon. Zhalia invoked King Basilisk to fight, but the two colossi easily sent King Basilisk back to its Amulet. Zhalia then invoked Gareon and Hoplite, who were likewise be sent back to their Amulets. When Dante eventually came back to consciousness and invoked Caliban and Metagolem, his two Titans were able to defeat both Undergolem Titans.
When Grier led the Huntik team to the Professor's Castle to obtain Rassimov's file, Eathon the dog, under the care of Hoffman, who is now serving Wilder, invoked his two Undergolem Titans. They fought alongside Doberman against Powerbonded Baselaird and Megataur. One Undergolem was defeated by Baselaird while the other overpowered and defeated Megataur. The remaining Undergolem Titan attacked Baselaird but was thrown back and defeated.
On the side of good, an Undergolem Titan was used to fight a Breaker Titan.
Undergolem can phase into a stone form, which restricts his movement, but it also renders him virtually invulnerable. According to Sophie Casterwill, Undergolem is a very powerful Titan being that he can fight for hours without getting tired and becomes more powerful the longer he fights.
